A major determinant of the resting membrane potential necessary for the
transmission of nercve impulses is the ratio between:
A) intracellular and extracellular Na+
B) intracellular and extracellular K+
C) instracellular Na+ and extracellular K+
D) intracellular K+ and extracellular Na+
- answer-Ans: B- intracellular and extracellular K+
A patient diagnosed with diabetic ketoacidosis (DKA) has the following laboratory
values: arterial pH 7.20, serum glucose 500 mg/dl, positive urine glucose and
ketones, serum postassium (K+) 2 mEq/L, and serum sodium (Na+) 130 mEq/L.
The patient reports that he has been sick with the "flu" for a week. What
relationship do these values have to his insulin deficiency?
A) increased glucose use causes the shift of fluid from the intravascular to the
intracellular space
B) decreased glucose use causes fatty acid use, ketogenesis, metabolic acidosis,
and osmotic diuresis
C) increased glucose and fatty acids stimulate renal diuresis, electrolyte loss, and
metabolic alkalosis
D) decreased glucose use results in protein catabolism, tissue wasting, respiratory
acidosis, and electrolyte loss
- answer-Ans: B- decreased glucose use causes fatty acid use, ketogenesis,
metabolic acidosis, and osmotic diuresis
A person diagnosed with type 1 diabetes experiences hunger, lightheadedness,
tachycardia, pallor, headache, and confusion. The most probable cause of these
symptoms is:
A) hyperglycemia caused by incorrect insulin administration
B) the dawn phenomenon from eating a snack before bedtime
C) hypoglycemia caused by increased exercise
, D) Somogyi effect from insulin sensitivity
- answer-Ans: C- hypoglycemia caused by increased exercise
At the arterial end of capillaries, fluid moves from the intravascular space into the
interstitial space because:
A) the interstitial hydrostatic pressure is higher than the capillary hydrostatic
pressure
B) the capillary hydrostatic pressure is higher than then capillary oncotic pressure
C) the interstitial oncotic pressure is higher than the interstitial hydrostatic pressure
D) the capillary oncotic pressure is lower than the interstitial hydrostatic pressure
- answer-Ans: B- the capillary hydrostatic pressure is higher than then capillary
oncotic pressure
Atheromatous plaques are most commonly found:
A) in larger veins
B) near capillary sphincters
C) at branches of arteries
D) on the venous sinuses
- answer-Ans: C- at branches of arteries
Carcinoma in situ is characterized by which change?
A) cells have broken through the local basement membrane
B) cell have invaded immediate surrounding tissue
C) cell remain localized in the glandular or squamous cells
D) cellular and tissue alterations indicate dysplasia
- answer-Ans: C- cells remain localized in the glandular and squamous cells
common hay fever is expressed through a reaction that is mediated by which class
of immunoglobulins?
A) immunoglobulin E (IgE)
B) immunoglobulin G (IgG)
C) immunoglobulin M (IgM)
D) T cells
- answer-Ans: A- immunoglobulin E (IgE)
Considering the hypothalamus, a fever is produced by:
